On modern Volkswagen and Audi platforms, the accessory drive belt (often referred to as a serpentine or V-ribbed belt) routes rotational power from the crankshaft to vital engine accessories, including the alternator and the air conditioning compressor. To ensure this belt grips the pulleys tightly under heavy electrical or A/C loads, a spring-loaded automatic belt tensioner applies constant, firm pressure against the outside of the belt.
Over tens of thousands of miles, the heavy-duty internal torsion spring inside the tensioner housing weakens and loses its factory tension. Furthermore, the sealed ball bearings inside the plastic or metal idler pulley dry out and fail. Symptoms of a failing belt tensioner include a loud, high-pitched "chirping" or squealing noise from the passenger side of the engine bay (especially during cold starts or when the A/C compressor engages), erratic alternator charging output, and visible belt fluttering or slapping while the engine is idling. If the tensioner fails completely and the belt snaps or derails, you will instantly lose all electrical charging and climate control, leaving you stranded.
Replacing your worn, bouncing factory tensioner with this premium OE-quality automatic tensioner from Febi Bilstein restores locked-down belt tension, guaranteeing quiet operation and reliable accessory performance.
Features:
Complete automatic accessory belt tensioner assembly featuring an integrated pulley and pre-loaded internal torsion spring
Cures cold-start belt squeal, rhythmic chirping, and erratic belt fluttering
Restores reliable power transfer to the alternator and A/C compressor
Precision-manufactured ball bearings ensure a long, perfectly quiet service life
